Here they come again.

Those still-missing Donald J. Trump tax returns have returned to front row of discussion topics relating to the Russian probe into the president’s 2016 campaign.

Trump hasn’t released them. He has broken a 40-year streak of disclosures from presidential candidates. He keeps saying he’s “under audit” by the Internal Revenue Service.

But wait! Special counsel Robert Mueller is now thought to be examining the Trump business empire’s dealings that might have something to do with the Russian government, which has been linked to allegations that it sought to influence the 2016 presidential election outcome.

Won’t those tax returns tell the public whether Trump’s businesses had any skin in the game? Won’t they reveal the truth? Couldn’t they possibly clear the air? Might they tell us that Trump has been truthful, that he has no business dealings with Russia?

Or, might they tell us something else?

I know I’m repeating myself. That’s too bad. Those tax returns need to go before the public.
